This is by far the best Empire at war mod I have ever played. Thank you guys so much for making it, and for caring enough to do updates and expanding on the mod. Many, many thanks to you. Can't wait to see what you can do with Sins of a solar empire.

Please can you provide more information on what your problem is (which version of Forces of Corruption, which patches you have installed, which version of the mod download you used, what happens when you launch the mod, etc).
